I completely agree with you. Lots of people always ask why I just don't put Bobo down, because he is 15 now and all his life has had a snotting problem. But those people just have no idea what it is to love a cat like your own kid. And being 15 years old, Bobo is still young looking, he will play with me and shows lots of health and energy. I think its a sin to put an animal down just because its old, if its healthy then why put it down?

Maybe sometime you can teach your friend a good lesson.
